Please refer to FIG. 2, which is a flowchart of a positioning method provided by an embodiment of the present application, and the positioning method is applied to a location management function (Location Management Function, LMF). As shown in Figure 2, the positioning method includes the following steps:

Step 201: The LMF transmits request information, where the transmission request information includes at least one of receiving first request information sent by a first device and sending second request information to a network-side device.

Wherein, the first request information and the second request information are used to request a positioning reference signal (On-demand Positioning Reference Signal, On-demand PRS) to be sent on demand.

Optionally, in an implementation manner, the LMF receives the first request information sent by the first device. For example, when the first device has a positioning requirement, the first device sends the first request information to the LMF to request the LMF. On-demand PRS; or, after the first device performs positioning measurement or position calculation, because the measurement or position information cannot meet the demand, the first device sends the first request information to the LMF to request the On-demand PRS from the LMF. Further, after receiving the first request information sent by the first device, the LMF may feed back the first response information to the first device, so as to respond to the first request information of the first device, that is, to respond to the first request information of the first device. On-demand PRS requested by the device.

It should be noted that, in this embodiment of the present application, the first device may include but is not limited to user equipment (User Equipment, UE), road side unit (Road Side Unit, RSU), relay node (Relay Node, RN) Wait. For example, terminals include mobile phones, tablet computers, wearable devices or vehicle-mounted devices, pedestrian terminals, reference terminals for calibration and other terminal-side devices; relay nodes include Integrated Access and Backhaul (IAB) and other relay equipment.

Optionally, in another implementation manner, the LMF sends the second request information to the network side device. For example, the LMF may send the second request information for requesting the On-demand PRS to the network-side device based on its own positioning requirements; or, after the LMF obtains the positioning measurement information or the position calculation, the measurement or position information cannot meet the requirements. , the LMF sends the second request information for requesting the On-demand PRS to the network-side device; or, the LMF may also send the second request to the network-side device when receiving the first request information sent by the first device information. Further, after receiving the second request information sent by the LMF, the network-side device may send the second response information to the LMF to respond to the second request information, that is, to respond to the On-demand PRS of the LMF. .

Optionally, in another implementation manner, the LMF receives the first request information sent by the first device, and then sends the second request information to the network side device. That is, the first device sends the first request information to the LMF to request the On-demand PRS from the LMF, and the LMF may send the second request information to the network side device after receiving the first request information sent by the first device . Further, the LMF receives the response information fed back by the network side device, and may feed back the response information as the first response information to the first device, so as to respond to the first request information of the first device.

It should be noted that, the On-demand PRS may refer to flexibly increasing or decreasing the PRS configuration specifically for the positioning requirements of one or some first devices. For example, a network-side device deploys a PRS with a smaller bandwidth, and for a UE that requires higher positioning accuracy, a dedicated PRS with a larger bandwidth is configured for the UE through signaling, that is, the UE's On-demand PRS. In this way, it is also possible to flexibly configure the required PRS for the first device according to the actual requirements of the first device, so that the configuration of the PRS for the first device is more flexible and the waste of resources is avoided.

It should be noted that the second On-demand PRS configuration information may be different from the first On-demand PRS configuration information; or the second On-demand PRS configuration information may also be the same as the first On-demand PRS configuration information The -demand PRS configuration information is the same. For example, the LMF receives the first request information sent by the first device, the first request information includes the first On-demand PRS configuration information, and the LMF sends the network-side device based on the first request information. The second request information, in this case, the second On-demand PRS configuration information included in the second request information may be the same as the first On-demand PRS configuration information; in another case, the LMF receives The LMF coordinates and processes the first request information sent by the one or more first devices according to the first request information of the one or more first devices, and determines the second request information, which is different from the first request information.

Optionally, the On-demand PRS first closing information or the On-demand PRS second closing information is used to request at least one of the following:

The request to restore the PRS pattern is the On-demand PRS transmission of the first pattern, and the first pattern is the pre-configured default beam pattern or the PRS beam pattern when the On-demand PRS transmission is not enabled.

The second preconfigured On-demand PRS includes at least one of the following parameters: bandwidth, period, beam direction, QCL relationship, TCI relationship, beam granularity, beam pattern, repetition factor, and muting mode. The second pre-configured On-demand PRS may be a set of pre-configured PRS configurations capable of guaranteeing the most basic positioning function, for example, including a bandwidth, and the bandwidth may be 10 kHz or 20 kHz, or the bandwidth may be 24PRB or 24× 4×nPRB (n is an integer greater than 1), etc.; or may also include a period, which may be 2u× ^10240slot , or 2u×5120slot, etc., where ^u is the subcarrier spacing; or may also include beam granularity , the beam granularity may be one transmit beam, or two transmit beams, or four transmit beams, or the like.

Wherein, the default bandwidth may also refer to a bandwidth preconfigured by the core network or a higher layer or a network side device.

It can be understood that, when the On-demand PRS first closing information requests to restore the On-demand PRS transmission to the first period, the first period is also different from the period when the On-demand PRS transmission is turned on. When the On-demand PRS first shutdown information requests to resume the On-demand PRS transmission under the first beam direction, the first beam direction is also different from the beam direction when the On-demand PRS transmission is turned on. The first beam direction may also be understood as a first beam angle. Optionally, the first beam angle may be the center angle of the beam, or may be other information indicating the beam angle. In addition, when the On-demand PRS first closing information requests to restore the On-demand PRS transmission to the first beam granularity, the first beam granularity is different from the beam granularity corresponding to the On-demand PRS transmission; the first beam granularity The beam granularity may be transmit beam granularity and/or receive beam granularity.

Understandably, the On-demand PRS first closing information or the On-demand PRS second closing information is to meet the requirements in some scenarios with less positioning requirements, such as late at night or in an empty and unoccupied area, The PRS configuration needs to be reduced to achieve the purpose of saving energy and reducing resource overhead. However, if the transmission of the PRS is completely disabled, it will not be able to locate in time when there is an urgent positioning requirement. Therefore, the shutdown information is a request to resume PRS transmission under certain configurations, which can also meet burst or basic positioning requirements under the condition of saving energy and reducing resource overhead.
